Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a multi-strand stranding machine for wires and cables. Background Technology

[0002] A wire and cable stranding machine is a specialized device used to strand multiple strands of conductors or metal wires into cable cores according to specific rules. It achieves spiral winding of the wires through mechanical rotation, improving the flexibility, tensile strength and electromagnetic shielding performance of the cable, and reducing the volume of the wires and cables, making them easier to transport.

[0003] A search revealed a cable stranding device with publication number CN222785094U, which uses an oil brushing component to evenly apply lubricating oil to the cable surface, thereby reducing friction between the cable and the through hole and the collecting ring, preventing cable damage, and also reducing wear on the through hole and the collecting ring.

[0004] However, when the above solution can no longer be used, the sealing cap needs to be removed before it can be replaced. Since the sealing cap is locked by multiple fixing screws, each of the fixing screws needs to be removed before replacement, which makes the replacement of the oil-absorbing cotton ring time-consuming and greatly affects the overall convenience.

[0005] Based on this, we propose a multi-strand stranding machine for wires and cables. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a multi-strand stranding machine for wires and cables, which solves the technical problem in the prior art that, because the sealing cover is locked by multiple fixing screws, multiple fixing screws need to be removed one by one before replacement, making the replacement of the oiling cotton ring time-consuming and greatly affecting the overall convenience.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0033] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0034] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0037] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] like Figures 1-5 As shown, it illustrates a multi-strand stranding machine for wires and cables according to one embodiment of the present invention.

[0039] In some examples, including:

[0040] Support base 1, support frame 2 is fixedly connected to one end of the top of support base 1, support plate 3 is fixedly connected to the top of support frame 2, multiple through coils 4 are fixedly connected to the outside of support plate 3, each through coil 4 has an open assembly cavity 5, and the assembly cavity 5 is filled with oil-brushing cotton rings 6.

[0041] The sealing component 7 is assembled on one side of the support plate 3 and is used to cooperate with the coil 4 to close the assembly cavity 5.

[0042] The upright frame 8 is fixedly connected to the other end of the top of the support base 1, and a collection ring 9 is fixedly connected to the top of the upright frame 8;

[0043] The stranding assembly 10 is assembled in the middle of the top of the support base 1 and is used to strand the cable core wires transmitted through the coil 4.

[0044] For example, such as Figure 3 As shown, each pass coil 4 is fixedly connected to an oil injection pipe that communicates with the assembly cavity 5 at its top end. The top end of the oil injection pipe is provided with a sealing cap. With the setting of the pass coil 4, when the lubricating oil at the brush cotton ring 6 is insufficient, lubricating oil can be injected into the brush cotton ring 6 through the oil injection pipe, thereby ensuring the application effect of the assembly cavity 5. With the setting of the sealing cap, the oil injection pipe can be sealed by the sealing cap when it is not in use. In this embodiment, the top end of the outer side of the oil injection pipe is provided with an external thread, the bottom end of the sealing cap is provided with an internal thread, and the sealing cap is connected to the external thread through the internal thread.

[0045] For example, such as Figure 3 and Figure 4 As shown, the sealing component 7 includes:

[0046] The central shaft 11 is rotatably connected to the middle of the support plate 3. The end of the central shaft 11 near the opening of the assembly cavity 5 is fixedly connected to the transmission disk 12. The outer side of the transmission disk 12 is fixedly connected to the sealing plate 13 corresponding to the through coil 4.

[0047] An eccentric plate 14 is fixedly connected to the end of the central shaft 11 away from the transmission disc 12. A guide groove 15 is provided in the middle of the eccentric plate 14. A transmission frame 16 is fixedly connected to the end of the support plate 3 near the eccentric plate 14. A transmission screw 17 is vertically rotatably connected to the inner side of the transmission frame 16. A displacement push plate 18 is threadedly connected to the outer side of the transmission screw 17, and one end of the displacement push plate 18 is also movably connected to the inside of the guide groove 15.

[0048] For example, such as Figure 4 As shown, the end of the sealing plate 13 away from the transmission disc 12 is circular, and a sealing ring is fixedly connected to the end of the sealing plate 13 away from the transmission disc 12. Due to the structural characteristics of the end of the sealing plate 13 away from the transmission disc 12, it can better fit the contour of the coil 4. The sealing ring can seal the connection between the sealing plate 13 and the coil 4, preventing the lubricating oil at the brush cotton ring 6 from flowing out of the gap. The sealing ring can be made of rubber.

[0049] For example, such as Figure 4 As shown, a linear guide rod is vertically fixedly connected to the inner side of the transmission frame 16, and the displacement push plate 18 is also slidably connected to the outer side of the linear guide rod. By setting the linear guide rod, the vertical displacement of the displacement push plate 18 can be guided, preventing the displacement push plate 18 from rotating with the transmission screw 17.

[0050] For example, such as Figure 4 As shown, a linkage pin is fixedly connected to one end of the displacement push plate 18, and the displacement push plate 18 is movably connected to the inside of the guide groove 15 through the linkage pin. With the linkage pin, during the vertical displacement of the displacement push plate 18, the linkage pin can press the eccentric plate 14, causing the eccentric plate 14 to drive the central shaft 11 to rotate. At the same time, a wear-resistant coating is provided on the linkage pin to reduce the wear of the linkage pin.

[0051] like Figures 1-5 As shown, it illustrates the twisting assembly 10 in another embodiment of the present invention.

[0052] In some examples, the twisting assembly 10 includes:

[0053] The twisting frame 19 is fixedly connected to the middle of the top of the support base 1. The top of the twisting frame 19 is rotatably connected to the twisting disc 20. The outer side of the twisting disc 20 is provided with a wire passing hole 21 corresponding to the wire passing coil 4.

[0054] A drive motor 22 is fixedly connected to the top of the winch frame 19. A drive spur gear 23 is fixedly connected to the output end of the drive motor 22. A moving gear ring 24 is fixedly connected to the outer side of the winch disc 20, and the moving gear ring 24 meshes with the drive spur gear 23.

[0055] For example, such as Figure 5 As shown, a positioning seat is fixedly connected to the top of the twisting frame 19, and the drive motor 22 is bolted to one end of the positioning seat. The positioning seat enables the twisting frame 19 to be effectively assembled, ensuring the stability of the drive motor 22.

[0056] Working principle: First, the cable core wire is passed through the coil 4 and the corresponding wire hole 21, and then passes out from the collecting ring 9. Subsequently, the drive motor 22 is started to cause the drive spur gear 23 to move the matching gear ring 24, which in turn drives the stranding disc 20 to rotate under the support of the stranding frame 19. Since the core wire is located inside the wire hole 21, when the stranding disc 20 continues to rotate, the multiple core wires can be stranded under the support of the collecting ring 9.

[0057] Furthermore, when the core wire is transmitted inside the coil 4, it can carry away some of the lubricating oil absorbed at the oil brushing cotton ring 6, thereby reducing the loss of the core wire transmission. When the oil brushing cotton ring 6 can no longer be used, the transmission screw 17 is rotated. With the connection between the transmission screw 17 and the displacement push plate 18, the displacement push plate 18 can be vertically displaced along the transmission screw 17 and press the eccentric plate 14. Since the eccentric plate 14 is supported by the central shaft 11, it can drive the transmission disk 12 to rotate with the help of the central shaft 11, causing the sealing plate 13 to move away from the corresponding coil 4, releasing the seal on the assembly cavity 5, so as to expose the assembly cavity 5. Then the oil brushing cotton ring 6 can be removed and replaced.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
